Abstract

Using the method of accelerating GRC ageing, the effects of waste concrete and fly ash on flexural Strength and durability of GRC were researched. The results show that the durability of GRC can be improved to some extent when 30% of natural sand in GRC was replaced by waste concrete, but the improvement on the durability of GRC was limited when 20% of cement was replaced by flyash. The improving effect on the durability of GRC with 30% of natural sand replaced by waste concrete , is greater than the one with 20% ordinary portland cement replaced by fly ash, and the effect is greater when natural sand and cement are replaced simultaneously by waste concrete and fly ash with the replacement rate mentioned above.
